I downloaded the Sabertooth-Z77-Memory-QVL.pdf from Asus and for DDR3 1600 Qualified Vendors List the only Mushkins listed are 996805(XMP) 4GB (2 x 2GB) with timings of 6-8-6-24 @ 1.65v. I guess these blacklines recommendations come from personal experience which I'll get behind.

And I'm in total agreement that these would look rather nice with the sabertooth armor as backdrop. Damn you guys aint kidding RAM these days is cheap. I paid double the price for only 4GB of DDR2 4 years back. Well not quite double 4GB I think cost $129 back then.
